ABSTRACT

A system and method for virtual processor customization based upon the particular workload placed upon the virtual processor by one or more execution contexts within a given program or process. The customization serves to optimize the virtual processor architecture based upon a determination as to the size and/or type or virtual execution registers optimally suited for supporting a given execution context. This results in a time-variant processor architecture comprised of a virtual processor base and a virtual execution context.

BACKGROUND OF THE INVENTION

In the field of microprocessor system architecture and design, maximizing the utilization of the processing capabilities of a given processor core is a crucial with respect to the performance and productivity of computing system. One of the most widely utilized approaches to accomplish this goal is the utilization of microprocessor systems that employ simultaneous multithreading (“SMT”) an architecture that enables a single core to intelligently process two separate tasks or “threads” simultaneously.

FIG. 1A provides a simplified representation of a single-core microprocessor system 100 that utilizes SMT. As shown, in a first configuration core logic 102 is switchably linked (104) to register grouping A (106) and data path 108. Register grouping A stores instructions and data defining a first processor state for microprocessor system 100. Core logic 102 then utilizes its internal resources (e.g., Adder, Arithmetic Logic Unit) to process instructions and data, acquired from register grouping A, and returns results of the processing to register grouping A via data path 110. As internal resources within core logic 102 become available to accept instructions and data from register grouping B (112) (a condition that can occur while other internal resources of core logic 102 are still processing the instructions/data acquired from register grouping A), core logic is switchably linked (104) to register grouping B (112) (see FIG. 1B), register grouping B stores instructions and data defining a second processor state for microprocessor system 100. As shown, in this second configuration, core logic 102 is linked (104) to register grouping B (112) and data path 114 to permit the fetching of instructions and data from register grouping B. The available internal resources of core logic 102 can then process the instructions and data acquired from register grouping B (returning processing results to register grouping B via data path 116). The selective utilization of Register groupings A and B by single-core microprocessor system 100 enables the internal resources of core logic 102 to appear to be simultaneously processing instructions and data acquired from both register groupings (simultaneous multithread processing).

Although SMT processing enables a single physical processor to perform as if there were two separate logical processors within the microprocessor system, SMT is still constrained by the physical limitations of the associated register groupings (register groupings A and B in the above example). Within a given microprocessor, these associated register groupings are physical register groupings fabricated within the same monolithic semiconductor structure as the core logic. These physical register groupings have a fixed size and structure that dictate the amount of data that may be stored within them, and the manner in which such data can be stored and/or accessed. These register groupings are fixed, physical semiconductor structures within the microprocessor and cannot be modified or reconfigured. In addition, the processor's instruction set which defines how these fixed register groupings are addressed and accessed is also static, and cannot be reconfigured or altered.

The physical register groupings within modern microprocessors can each consist of a large number of individual registers. These sizable register groupings, combined with the static nature of the instruction for accessing the register groupings, typically result in a significant number of clock cycles being required for a given set of instructions or data to be acquired from the register grouping architecture and provided to a logic core. The larger the register grouping, the greater the possible clocking delay and consequential loss of processor efficiency.

Consequently, there exists a need for a system and method that provides the ability, at run-time, to dynamically define the configuration, capacity, and other aspects of the register files associated with one or more logic cores, and to provide the proper context to enable any associated logic core to access and execute the information contained in the dynamic register files, thereby achieving increased processing speed and efficiency.

DETAILED DESCRIPTION

FIG. 2 is a functional block diagram of a processor and execution memory system (200) supporting a preferred embodiment of a system and method utilizing dynamic register files. As shown, system 200 consists of processor 202 and virtual execution context memory 204. Processor 202 includes base register contexts 206, register context pointer 208, memory context pointer 210, configuration register 212. Virtual execution context memory 204 is defined by software in a configurable random-access memory storage system, such as a DRAM or SRAM. The execution context memory stores information indicative of a register context (214) and an associated or paired memory context (216). Register context information 214 can include information typically associated with defining a processor state (i.e., processing a given thread), such as constant registers 218, parameter registers 220, reference registers 222, general purpose registers 224 and local process registers 226. Similarly, memory context information 216 within execution context memory 204 can include information such as variable storage information 228 and environment chain information 230.

The functionality of the system depicted in FIG. 2 is similar to that of the system depicted in FIGS. 1A and 1B, in as much as the information stored in virtual execution context memory 204 defines the state of processor 202. However, there are numerous critical advantages offered by system 200. For example, virtual execution context memory 204, being a software-defined construct within RAM is not comprised of fixed physical registers fabricated within a monolithic semiconductor structure housing a fixed core logic. Rather, execution context memory 204 is configured to have precisely enough capacity to contain the register context information 214 and paired memory context information 216 that define a given state of processor 202. “Right-sizing” the amount of RAM allocated for each of the associated registers, variable storage and/or environmental chains to define and support a particular state of processor enables the information contained in virtual execution context memory 204 to be accessed very efficiently. This right-sizing can be performed at run-time so as to dynamically define the amount of memory within the configurable random-access memory storage system designated for each of the registers, chains and variable stores within execution context 204.

For example, if defining a particular processor state required 1 Mbytes of parameter register context information 214, then IM byte of space within random-access memory storage system would be designated for that purpose. Similarly, if 256 Kbytes of memory context information 216 was required to define a particular processor state, then 256 Kbytes of RAM would be designated for that purpose within virtual execution context memory 204. This permits processor 202 to access requisite information from execution context memory 204 without the inherent inefficiency introduced by a fixed physical register structure that is likely to have a capacity far in excess of what is required to support the register context information (214) or memory context information (216) required to define a particular processor state.

Register context pointer 208 within processor 202 provides the particular RAM address at which the register context information is stored. Similarly, processor 202's memory context pointer 210 provides the particular RAM address at which the memory context information is stored. The requisite context information is efficiently retrieved and processed, enabling processor 202 to efficiently assume a defined state and process an associated thread. This direct access of right-sized execution context information also permits processor 202 rapidly switch between one state or thread and another, offering greatly improved processor efficiency when compared to a conventional fixed register processor architecture.

The system and method disclosed above offer an additional advantage over conventional, fixed-in-silicon core and register processor architecture. In such conventional processor architecture, the stored memory context information relates to the entire platform. If such platform-wide information were to be breached, it could provide a basis for platform-wide unauthorized access and the compromising of all of the information associated with the platform. Contrastingly, the disclosed system and method utilize context pointers within a logical processor. These context pointers (register context, memory context, etc.) are not accessible outside of the execution context in which they reside. Furthermore, each pointer only provides direction to a specific RAM location and would not provide any indicia useful in attaining unauthorized platform-wide access. There is simply is no platform-wide information stored within the base registers. In fact, the architecture in the system described above fails to even have a platform that could be viewed as analogous (and therefore as vulnerable) to the physical semiconductor structure upon which present microprocessor technology is typically fabricated.

Processor 202 can be a processor utilizing a single core system (similar to the processor depicted in system 100 of FIGS. 1A and 1B), or a processor employing a multi-core architecture. Each of the cores being capable of utilizing SMT or a similar strategy to perform as two or more logical processors, wherein the state of a given a logical processor would be defined by the accessed register context information and memory context information. A functional block diagram of one such multi-logic core system (300) is illustrated in FIG. 3. As shown, system 300 includes six logical processors (302-312) configured to access virtual execution context memory 314. These logical processors each include base register context information (316-326), which although critical to the operation of processor 202, typically reside outside of the physical package housing the processors logic core(s) so as to enable them to be utilized by other active execution processes.

Each of the logical processors (302-312) respectively accesses one pair of register context information 328-338 and memory context information 340-350 within virtual execution context memory 314. The logical processors then each execute the thread defined by the respective paired register and memory context information. As internal resources within a logical processor become available to accept instructions and data associated with a different thread, the logical processor can access alternate register and memory context information pairs within virtual execution context memory 314. For example, assume that resources within logical processor 302 become available after completing the processing of a thread that was defined by register context information 328 and memory context information 340. Virtual processor 302 could then be utilized to execute a thread defined by accessing register context information 330 and memory context information 342.

As previously stated, the paired register context and memory context information is stored within RAM, and consequently it will be understood that that the number of such pairings is limited only by the size of the available RAM. FIG. 4 provides a functional block diagram of a system (400) wherein virtual execution context memory 402 includes paired register and memory context information 408 through 4 nn. These right-sized register and memory context pairings define a different processor state for processing a particular thread. Each of the register and memory context pairings is accessible by any one of logical processors 402-4 mm, utilizing register and memory context pointer information stored within each logical processor. This enables any available resources within any one of the six logical processors to assume the state and execute the thread defined by any one the of the register and memory context pairings stored within virtual execution context memory 402.

An additional embodiment of the above system and method utilizes a virtual processor in conjunction with execution context memory. As shown in FIG. 5A, virtual processor system 500 a is similar to the system depicted in FIG. 2. Virtual execution context memory 504 is a software-defined construct within RAM and configured at the initial run-time of a given process or program to have precisely enough capacity to contain the register context information 514 and paired memory context information 516 required to support the operations that will be executed over the entirety of the given process/program. Register context pointer 508 provides the particular RAM address at which the register context information is stored, and memory context pointer 510 provides the particular RAM address at which the memory context information is stored. However, unlike the system of FIG. 2, the processor (502) in which these context pointers reside is a virtual processor. Virtual processor 502 is comprised of information indicative of a register context pointer (508), a memory context pointer (510). Virtual processor 502 can also include other configuration register information (512) required to specify a given virtual processor state, as well as virtual processor identification information (518), which would serve to distinguish between individual virtual processors in systems employing multiple virtual processors. As with the virtual execution context information (514) of system 500 a, the information comprising virtual processor 502 is stored within RAM (see FIG. 5B). The processor is effectively virtualized in a manner similar to that of a thread or processor state, and the virtual processor information is processed one or more logic cores as assets become available. In the system (500 b) depicted in FIG. 5B, the information representing the virtual processor can be stored within the same RAM (520) utilized for storage of the virtual execution context information.

In all of the systems and methods that have been described, the state and configuration of the processor (be it virtual or otherwise) is defined at the run-time of a given process or program. That is, the number and types of registers, as well as the resources to support the requisite memory context, are defined so that the operations executed over the entirety of the given process/program will be supported. Although this specification of these resources is can be viewed as dynamic as it is a function of the particular resource requirements for a specific process/program, and will be redefined prior the execution of a new process/program by the virtual processor, the definition remains static throughout the execution of any given process or program.

The embodiment of the invention illustrated in FIG. 6 provides for a system and method wherein the particular resources supporting a process/program are dynamically adjusted to accommodate the workload at any given point within a process/program. This effectively changes the very geometry of the virtual processor executing a process/program as a function of processor workload, thereby enabling execution efficiency and security to be further optimized.

As shown, in FIG. 6, a system 600 includes virtual processor 602 and virtual execution context memory 604. Virtual processor 602 is comprised of information indicative of a compiler (608), register context pointer (610), a memory context pointer (612). Virtual processor 602 may also include other configuration register information (614) required to specify a given virtual processor state, as well as virtual processor identification information (616), which would serve to distinguish between individual virtual processors in systems employing multiple virtual processors. Virtual execution context memory 604 is a software-defined construct within RAM and includes register context information 618 and paired memory context information 620 which support the operations that will be executed during a given process/program. The primary operation and interaction of the various components of system 600 are similar to the like-named components of system 500 b (FIG. 5B). However, system 600 employs a compiler adapted to determine the precise number and size of the register resources required to support each instruction in the stream of instructions that comprises a given process/program. Compiler 608 is a software construct adapted to interpret a language source code, and emits a code file comprised of machine code targeted for a specific execution environment. The compiler can be resident in the same system that supports virtual processor 602 and/or execution context memory 604, or be supported by a wholly separate system.

The compiler in system 600 operates to provide a code file defining the specific execution environment is for virtual processor 502. This code file would include at least one base instruction set (“IS 0”) to enable the initialization of the virtual processor. Compiler 608 is further adapted to provide one or more additional instruction sets so as to configure virtual processor 602 to support both fixed length (622) and/or variable (624) length virtual execution registers. As the compiler processes each instruction, it computes the optimal number, type and size of the registers required to support and execute that particular instruction, or subset of instructions comprising a given execution context with the overall process/program.

In a first embodiment, system 600 is utilized to allocate a set of fixed registers as a function of particular individual instructions within a given execution context. This could be implemented as a function of a single parameter indicative of the number of static registers to be allocated. In this embodiment, all registers are of a uniform size, and therefore the size is inherently known. So, an instruction could for example allocate 64 static registers, starting at register offset 00, and being continuous through register 63. These 64 registers remain allocated until the termination of the execution context. In a 32-bit processor system, the register width would most likely be 32 bits; in a 64-bit processor system, the register width would most likely be 64 bits.

System 600 could also be adapted to allocate multiple types of registers on the basis of particular individual instructions within a given execution context. As shown in FIG. 6, these registers can include general-purpose registers, constant registers, parameter registers, and reference registers. This allocation can be executed on the basis of an instruction comprised of a single parameter, A=15. This parameter would be interpreted by system 600 as specifying the allocation of 15 general purpose registers, 15 constant registers, 15 parameter registers, and 15 reference register. This makes for a compact and efficient instruction, but runs the risk of wasting register space for the register types that do not require the maximum count of 15.

An alternate methodology could employ an instruction having a more complex structure and specify the allocation use a form of A=(20, 50, 12, 30). This would be indicative of the allocation 20 general purpose registers, 50 constant registers, 12 parameter registers, and 30 reference registers. Each of these registers would be of identical width.

Yet another instruction schema suitable for use with system 600 supports the allocation of registers having unequal widths. For example, assume system 600 has a somewhat limited address space, but the capability to support large numeric representations. In such in architecture the width of a general-purpose registers, constant registers, and parameter registers would be large, such as 128 bits, while the reference registers storing addresses would be a more modest 32 bits. An allocation instruction of the form A=[(20, 128), (50, 128), (12, 128), (30, 32)] would result in the allocation of 20 128-bit general purpose registers, 50 128-bit constant registers, 12 128-bit parameter registers, and 30 32-bit reference registers. This amount of memory required to hold each register type being dictated by the register type itself. This optimizes the memory allocation for the register set, as the byte offsets to the registers can be easily calculated from the register number and register type, and maintains a consistent instruction set register numbering scheme across all register types.

The allocation instruction could also be of a format that specified the register width along with the register type, so as to provide an even more dynamic and flexible use of register memory. For example, many machine learning programs utilize a 16-bit arithmetic width to support high-speed calculations while sacrificing a certain degree of accuracy. In executing such a program, an architecture could be allocated to permit general-purpose, constant, and parameter registers to be of varying widths. An allocation instruction of A:=[[(20 64), (20 16)], [(25 64), (25 16)], (12 64), (30 64)] would be indicative of the following register configuration:

-   -   20 64-bit general purpose registers;     -   20 16-bit general purpose registers;     -   25 64-bit constant registers;     -   25 16-bit constant registers;     -   12 64-bit parameter registers; and     -   30 64-bit reference registers.         The specific execution context supported by the specified         registers being precisely configured for the machine learning         task at hand.

An alternate allocation command sequence of four separate instructions wherein each one specified type, quantity and width of the requisite registers could also achieve the same end result. For example:

-   -   A=0 20 64, 0 20 16;     -   A=1 25 64, 1 25 16;     -   A=2 12 64; and     -   A=3 30 64.         In this instruction format, the first number of the ASRS         instruction delineates the type; 0=General Purpose, 1=Constant,         2=Parameter, 3=Reference.

It should also be understood that although the register allocation systems, parameters and processes described above were focused upon providing the allocation of particular registers having a type and a size (width) based primarily upon optimizing the execution of particular instructions within a given execution context, the inherent security aspects provided by such are significant. The very nature of the register allocation system and processes discussed above is dynamic in the time domain. Any state or information available at a given time is transient. An external entity observing or accessing this dynamic system (perhaps without permission) would be observing what would appear to be an unstable system, presenting information that appeared to vary randomly in size and location. Without the proper context for a given state of the dynamic system (which would be wholly unavailable to an unauthorized third party), the information would likely yield little or no discernable intelligence with respect to the process being executed. The inherent security aspects of this dynamism are obvious. Consequently, utilization of such a system could be motivated in whole or in part by the provision of a secure virtual environment for the execution of particularly sensitive or private processes.

As noted above, compiler 608 of system 6X) operates to provide a code file which defines the specific execution environment for virtual processor 502. In particular, this code file would at a minimum include a base instruction set (“IS 0”) to initialize the virtual processor, and could also provide one or more additional instruction sets so as to configure virtual processor 602 for a specific environment or set of tasks. The code file effectively defines and provides the execution context in which the processor will operate.

In a virtual processor system, such as system 600 of FIG. 6, the virtual processor can be conceptualized as split into two separate components: a virtual processor base 702 (“VPB”), and a virtual execution context (“VEC”) within a random-access memory (706) (see FIG. 7A). Both the VEC and the VPB are typically represented as objects comprised of parameters aggregated and arranged by a constructor (710). This constructor, not unlike the compiler of system 600, is a software construct. Constructor 710 is adapted to configure virtual processor components, and can be resident in the same system that supports virtual processor and/or execution context memory, or can be supported by a wholly separate system. The particular parameters comprising the virtual processor components may include initial static register configuration, initial dynamic register configuration, along with other context information.

Upon creation of the VPB, the VPB is supplied with the necessary boot-strap instruction for the initiation of VEC execution. This instruction can be as simple as an address that the VPB's instruction pointer needs to point to the location of the required bootstrap code needed by the VEC to begin execution. However, it can prove advantageous to have the VPB also provide the code that the instruction pointer needs to point to in order to execution the bootstrap. The VPB points back to itself to obtain the initial code for execution. The VPB is initially self-sufficient.

In the simplest form a VEC could be constructed so as to comprise only of a base instruction set, IS 0 (712), to enable the initialization of the virtual processor. No specification of register allocations need be provided. Upon the VPB attaching to this base VEC (see FIG. 7B), the first instructions the executed would be those allocating the memory used for the processor workload contexts. The code provided by the system compiler could then dynamically reconfigure the BPB and/or VEC so as to optimize it for executing particular code. The compiler would have determined, during compilation, which values are to be kept in the register context, both static and dynamic, as well as what values need be kept in the memory context.

Secure items which are stored within the register context are only visible when the execution context is active and can only be manipulated by the instructions the virtual processor executes. As long as the VEC can refer to the next instruction via an instruction pointer, the boot process can continue, supported by the VPB instructions allocating the required resources prior to the memory being used.

Although the particular example discussed above dealt with an environment in which a virtual processor was employed, the creation of execution context information is also applicable to systems employing physical processors (those fabricated upon a physical medium). This physicality dictates that the memory constituting the available storage space for physical execution context information, is limited to a static size within the processor. If the processor is designed such that a separate memory bus attaches it to an external memory, the size of the available memory space may be substantially larger, but still static. The use of external memory for the storage of execution context information may also impact processor speed/performance as dictated by bus and memory access limitations.

A physical processor in such a system could establish a physical execution context in one of several manners. One particular approach would be analogous to the VEC constructor discussed above. An allocation of the requisite memory range from the available physical memory resources is made to the physical processor for storage of the required register context information. This allocation could be a default value, for example, 1K of memory. Every created physical execution context for the physical processor would be allocated the same amount of physical register context memory (a 1K block), assuming the static, finite memory resources were available to support such.

Another approach, also somewhat similar to the VEC context creation. In the physical processor, the instruction set defining the execution context information is stored in either read only memory, or a loadable control storage memory. In a system utilizing loadable memory, the allocation of the requisite memory would be performed as part of the boot process directed by the Basic Input/Output System (“BIOS”) or the Unified Extensible Firmware Interface (“UEFI”) embedded in the physical firmware. This gives rise to a dilemma of sorts, in as much as: How can BIOS or UEFI execute if no execution context for the physical processor exists? However, this seemingly paradoxical situation is actually encountered and dealt with regularly when a physical processor is reset. The processor's instruction pointer is initialized to a known value at which read only memory comprising the initial instruction set is known to reside. In this embodiment, there would be two instructions provided: i) create initial context; and ii) create execution context.

The create initial context instruction is the first instruction (IS 0) executed by the processor. IS 0 can be fetched explicitly from a location pointed to by a hard-coded instruction pointer, or it can be an implied instruction embedded as processor microcode automatically executed as the processor leaves a reset state, but prior to the fetching of a first instruction. Upon execution of this first instruction (actual or implied), an explicit instruction to create execution context is executed. This instruction must specify the resources to be allocated to support the newly created context information, and consequently may be too complex for storage and execution as an initial instruction for the processor. The first context is unique, as it defines and allocates the resources required for basic instruction fetching and execution by the processor.

An alternate approach would be one in which initial context gets assigned the entire resource pool. Then, as the system boots, the software instructs the reduction of the dynamic portions of the register context, freeing resources for allocation to others. This dynamic reduction approach ensures that sufficient resources exist for the boot process and relies on software to scale back utilized resources prior to instantiation of additional context processes. This approach is suitable for embedded or single purpose embodiments, wherein the bootstrap code is the application itself. It is also applicable to large-scale deployments leveraging the fact that the bootstrap process “owns everything” in the system and as the initialization process executes, it can step its way into the dynamic environment by managing the overall system resources.

A system for generating context execution information comprising: a constructor adapted to configure at least one virtual processor base and at least one virtual execution context, wherein the constructor is further adapted to: generate at least one boot-strap instruction; provide the at least one virtual processor base with the at least one generated boot-strap instruction; initiate the execution of the at least one virtual execution context in response to then reception of the at least one generated boot-strap instruction by the at least one virtual processor base; and retrieve and execute instructions from the at least one virtual execution context.
 20. The system of claim 1 wherein the at least one boot-strap instruction comprises a memory address at which code required to initiate a process comprising the at least one virtual execution context.
 21. The system of claim 1 wherein the instructions retrieved from the at least one virtual execution context comprise information for the optimization of the at least one virtual processor and the at least one virtual execution context for the execution of a particular code.
 22. The system of claim 1 wherein the at least one virtual processor is defined by parameters comprising at least one of the following: a specification of the initial static register configuration; and a specification of the initial dynamic register configuration.
 23. The system of claim 1 wherein the constructor and the at least one virtual processor base are supported by a common system.
 24. The system of claim 1 wherein the constructor and the at least one virtual processor base are each supported by separate systems.
 25. The system of claim 1 wherein the at least one virtual processor base and the at least one virtual execution context are both supported within a single physical addressable memory device.
 26. The system of claim 1 wherein the at least one virtual execution context is supported by an addressable memory linked to the at least one virtual processor base by a bus.
 27. The system of claim 1 wherein at least one of the at least one virtual processor base and at least one virtual execution context comprises at least one of the following: static random-access memory; dynamic random-access memory; and non-volatile memory.
